Atherton Bridge
Posted April 26, 2020, by Nick Boppel (nickboppel01 [at] gmail [dot] com)

As of last week, this bridge has been indefinitely closed to all traffic including pedestrians due to damage to the wooden deck caused by flooding. The truss superstructure itself appears to be intact, but there is no ETA on when or if the bridge will reopen to any form of public use.
